Abstract: A short sediment core Esdr1 from Shudu lake has been analysed of geochemistry elements and radionuclides. Accurate sediment chronology was established by 137Cs. Meteorological observation records reveal that climate changes experience two stages during past 44 years in the region of Shudu: a cold/wet stage during 1958～1983 a B.P, a warm/dry stage between 1983 and 2002. Climate changes reconstructed by Esdr1 core geochemical proxies are consistent with Meteorological observation records. Sediment in Shudu Hai documented in detail Regional climate changes and human activities which mean that the sediment from this lake could be the suitable archive for environment changes reconstruction in this region.
